ABOUT THE CHPA

Putting the energy user at the centre

CHPA Mission statement

Our vision is for an energy system that is dictated by the consumers' needs rather than one that dictates to them, creating a more local, efficient and less costly energy system

Areas of focus:

Combined heat and power

Sustainable energy services

District heating and cooling

THE ROLE OF CHP AND DISTRICT HEATING

Opportunity of energy inefficiency

Energy Flows in the Global

Electricity System

Source: IEA,CHP: Evaluating the Benefits of Greater Global Investment (2008).

2/3 of the fuel “we” use to produce power is wasted --

CHP can more than double this efficiency

Why is CHP more efficient?

CHP and security of supply

CHP provides lower costs and CO2

CHP in the UK1,900 CHP schemes in UK, with 1,500 in commercial and services sector

At least £200m new investment last year

6.4% of electricity generation

70% is natural gas

What is district heating?

District heating is technology neutral

Heat as part of an integrated energy system

District heating market

~50,000 dwellings on modern DH schemes

New build and retrofit planned projects will deliver a further 50-60,000 dwellings

Modern DH schemes

Block heating refurbishment

108 completed schemes: >50,000 dwellings & ~900,000m2 commercial

>50 schemes planned: ~50,000 dwellings and 350,000m2 commercial

CHPA Survey: Modern DH Schemes

377,000 dwellings in England on ‘district heating systems’ ≡ 2% of dwellings

Includes both large and building-level schemes

Potentials from Pöyry/AECOM for DECC (2009)3 to 8 million dwellings

15-26M m2 non-domestic floor space

Requires ‘de-risked’ cost of capital (3.5% SDR) and comprehensive application of carbon price

INDUSTRY INITIATIVES

Independent Heat Customer Protection scheme

Consultation now concluded

Voluntary scheme aims to launch by December 2014

Will set minimum standards for heat suppliers and customers

Customer service and reporting a fault or emergency

Joining and leaving procedures

Heat bill, heat charge calculations and heat charge comparator

Paying the heat bill and payment difficulties

Disconnection and re-connection process

Complaint handling and independent adjudication

Privacy policy and data protection

Heat Network Code of Practice

CIBSE and CHPA developing minimum technical standards for heat networks

Proposals currently out for consultation

Addressing issues related to the often too fragmented stages of delivery of a network

New small-scale CHP guidelines

CHP only provides benefits when it is installed and operated properly

Reputation risk to all parts of supply chain

Read and use CIBSE’s AM-12 Guidance

Energy audit to see if CHP right solution

Use reputable CHP supplier, with long-term O&M contract

Design properly to use CHP’s efficiency, low temperatures

Create a handover strategy with building users
